Definitions

• the hairdressers final purpose is in effect to realize by a hair disposition a style of hair-dressing adapted to the up to date taste and to the treated hair; such disposition is socalled a setting in the art.
• the hairdresser arranges Wet hair, previously curled by the permanent waving, in locks which he rolls at his will and dries when the whole of the operation is completed.
• the present invention aims to simplify and facilitate the hairdressers work for such hair setting which constitutes the essential part of his art, owing to the fact that it makes unnecessary the previous permanent waving proper of the hair and that it makes it possible to accomplish the hair setting in a single opera-tion while giving to the hair a better lasting which extends the duration of the hair-dressing in a noticeable manner.
• This invention has for a primary object a hair setting process eliminating any previous permanent waving, charaoterized by the fact that the hair is impregnated with an aqueous solution of a compound having a reducing effect analogous to that of mercaptans, so as to impart to the hair the desired plasticity, and having moreover the characteristics of a cation-active detergent which cleans the hair and comprises a fatty chain susceptible of adhering to the cleaned hair while giving the same a brightness and a suppleness which facilitate the hair setting, that such hair setting is performed after rinsing of the hair and that the hair is air dried so as to permit an oxidation which gives again to the set hair its natural elasticity.
• the present invention has for another object to provide a cation aotive addition salt of an amine, comprising a thiol group reducing the keratin disulphide bridges to put into practice the aforementioned hair setting process, said salt being characterized by the fact that it belongs to the general formula:
• R is a hydrogen atom or a lower alkyl radical comprising not more than 6 carbon atoms
• R" is a lower alkyl radical, any either of substituents 'R, R' being selected from hydrogen and a lower alkyl radical and the other being a water repelling fatty radical having from 8 to 24 carbon atoms and X being an acid anion harmless to the live hair and to the scalp.
• the compound according to this invention may be used advantageously in the state of an addition salt obtained by reacting this compound with an inorganic or organic acid.
• one object of the present invention is to provide a process for making a cation-active compound of the aforementioned Formula (I), characterized by the fact that it consists in bringing into reaction equimolecular amount of a mercaptan having the general formula:
• the reduced bridges SS- in a relatively low number by the application of these reducing surfaceactive products, may be rebuilt by the sole action of the oxygen of air during the conventional operations of drying in a draught, under a helmet, without using an oxidizing solution as in the case of a permanent waving.
• foaming cationic detergent properties allow them to be applied as a shampoo as it is applied in a conventional manner previously to the purely manual operation of hair-setting; so as to avoid, in particular, when first applied, any excessive dilution by water, after which the hair is rinsed and the hair-setting and drying operations are elfected according to the usual practice.
• the efiiciency of the amide formation may be increased by reacting under the same conditions as those mentioned above new amounts of ethyl thioglycolate, once or twice, taking into consideration the amount of non reacted amine.
• the product may be purified by using its insoluble cadmium salt (by reacting cadmium acetate) which can be separated and decomposed later by hydrogen sulphide.
• the practically pure product is thus obtained in the form of an aqueous solution.
• This product having an 85% purity was directly treated with lactic acid. There was obtained a gel, which was dissolved in water at a 30% to 35% concentration. This solution is used as a shampoo.
• An improved process for setting living hair without submitting the hair to a previous permanent waving which comprises, impregnating the hair with an aqueous solution of an addition salt of a member of the group consisting of the organic and inorganic acid salts of a compound having a general formula wherein R is a member of the group consisting of a hydrogen atom and a lower alkyl radical having not more than 6 carbon atoms, R" is a lower alkyl radical, and one of the substituents R and R is selected from the group consisting of a hydrogen atom and a lower alkyl radical, the other being a water repelling fatty acid radical having from 8 to 24 carbon atoms, the organic and inorganic acids being harmless to the live hair and to the scalp, said addition salt having a reducing action analogous to that of mercaptans, so as to impart to the hair the desired plasticity and having moreover the characteristics of a cation-active detergent which cleans the hair and com prises a fatty chain susceptible to adhere to the cleaned hair
• An improved process for setting live hair without submitting the hair to previous permanent waving which comprises, impregnating the hair with an aqueous solution of an addition salt of lactic acid, with a compound having a general formula wherein R is a member of the group consisting of a hydrogen atom and a lower alkyl radical having not more than 6 carbon atoms, R is a lower alkyl radical, and one of the substituents R and R, is selected from the group consisting of a hydrogen atom and a lower alkyl radical, the other being a water repelling fatty acid radical having from 8 to 24 carbon atoms, rinsing the hair so impregnated, separating the hair into individual locks, setting the hair in the form desired and allowing the hair to dry so as to permit oxidation to impart to the hair in a set condition its natural elasticity.
• An improved process for setting hair without submitting the hair to previous permanent waving which comprises impregnating the hair with an aqueous solution containing an addition salt of lactic acid with mercapto- N-lauryl-N-(Z-diethylaminoethyl) acetamide, rinsing the so impregnated hair, separating the hair into individual locks, setting the hair in the form desired and air drying the same to permit oxidation to impart to the hair in a set condition its natural elasticity.
• An improved process for setting hair without submitting the hair to previous permanent waving which comprises, impregnating the hair with an aqueous solution containing an addition salt of lactic acid with mercapto N (2 methyl,2 lauryl,aminoethyl) acetamide, rinsing the so impregnated hair, separating the hair into individual locks, setting the hair in the form desired and allowing the hair to dry so as to permit oxidation to impart to the hair in a set condition its natural elasticity.
